This invention relates to a lens mounting for eye glasses, spectacl sand the like in unich the bow connectin ing,` posts wardly, downwardly and upwardly entending,` arins preferably integral therewith to forni opp site loops at the rear of the posts so that eitherl arin of each loop inay be bent-laterally or forwardly, and rearwardly by ineans of a pair of pliers or other suitable tool for the purpose of adjusting and settingthe lenses the proper pupillary distance apart and also for adjusting the lenses and bridge piece of the bow forwardly and rearwadly relatively to eaeh other as niay be required to lit the eyes of the user.

entend downwardly in more or less ing planes at opposite sides of the bringe of the nose which necessitates the use of suitable nose guards to prevent irritation of the nose by the loops, and the inain object of roy invention is to support these nose guards upon the rearwardly extending olf- '1253 sets at the ends of the bow in such manner that they may be inoved out ot the way of the loops without displacement to perniit the nianipulation of tool in bending' or adjusting the offset arrns of the loops to properly im til' the lenses to the eyes.

@ther objects and use relating` to specitic parts of the mounting will be brought out in the follorfing` description.

ln the drawings:

ai Figures l and 2 are respectively, a top plan and a. side elevation of a. pair of lenses, and my improved mounting,` for connecting; the saine.

'T/ure 3 is an enlarged transverse vertical fla sectional v'ew through the central portion of the mounting showing' .one of the nose ards in its norinal position. Figure is an enlarged edge view of the detached in ou ntin yFigure an enlarged rear elevation of e mounting showing portions of the len. ,i i; olren away and also showi r nose Lequa-rds as swung upwardly away fr the adjacent loop to permit the of a 521 suitable tool for bending` or adjusting` the arins of the loop as may be required to properly tit the lenses to the eyes of the user without displacing the nose guards from the mounting.

is illustrated, this mounting comprises a pair el lens supporting posts the liens supper-rt-A is provided wit-a opposite rear' Serial No. 605,027.

bow or bridge piece '2 having its opposite ends offset rearwardly to forni pivotal pintles 7H for the nose guards, the rear ends of said pintles being bent downwardly, forwardly and upwardly to forin lll-shaped loops -3- below their respective pintles, the upper ends of the front arins as flof the loops being; offset forwardly at -6- and attached to the posts -l-H so that the pintles "7- and loops are cisposed at the rear of the plane of the lenses which permits the nose guards to be swung,` to norinal positions along the inner sides of the loops to positions above the loops which in turn perinits the use of pinchers or other suitable tools upon different portions of the loops for adj usting` the lenses without interference by the nose guards.

The lower ends as lof the loops constitute returned bends which permit the 5- to be adjusted by bending forwardly and rearwardly and also laterally toward and from each other to establish the desired relation between the bow Q- and lenses as A and also to properly adjust the distance between the centers of the lenses to conform to the pupillary distance of the user.

The specific forms ot these loops, therefore, greatly simplify and facilitate the various adjustments necessary to fit the lenses to the eyes of the users without disturbingthe shape of the bow or overstraining the connections between the lens posts and adjacent portions of the mounting and while they might be used as nose guards ,tor engaging opposite sides of the bridge of the nose to hold the mounting against lateral displacement, it is obvious that they would be rather uncomfortable, and in orde-r to maintain the utility of this particular forni of loops, and at the saine time to protect the nose against undue irritation, l have provided a pair of nose guards -9- of relatively thin and highljT resilient metal having; their upper ends provided with eyes lO- The nose guards Q are journaled at their upper ends upon the offset portions or pintles -faof the mounting to extend downwardly.therefrom practically the entire length of the loops .-3- and are preferably' bowed longitudinally toward each other for frictional engagement with opposite sides the bridge of the nose of the user.

iside ,im pivotal connection. of the eyes 10M with the ollset:` portions -7- the nose guards 9 are unattaehed to the loops and are free to swing inwardly and upwardly to the position shown by full lines at the right of Figure 5 out of the way of the loops to permit the arms of the loops to be bent forwardly or rearwardly or laterally as may be desired to lit the mounting to the nose and to properly position the lenses relatively to the eyes ol' the user, after whieh the nose guards d9- may ne swung downwardly to their normal positions with the lower ends resting against the inner faces of the corresponding ends of the loops.

3y constructing the loops -3- and their connections with the posts land bow 2M and assembling the nose guards upon the ol'l'set portion T- ot the loops in the mannerdeseribed, enables the nose guards to be used to protect the nose against irritation without in any way interfering with the free bending of the arms -lland Zito properly adjust the mounting and lenses to the nose and eyes.

Itis also evident that by making the bridge, as a whole connecting the posts -l-, of a single piece o' wire or equivalent bendable metal enables the oritige io lie easily adjusted by bending at any ol the bends all o'lE which greatly facilitates and expedites the work ot' adjusting the 1nonnting and lenses to lit the user and at' the same time retains the nose guards in position upon the mounting ready l'or use by simply swinging them down to their normal position.

I elaim:

ln a lens mounting l'or eye flaw having its ends ol'iset rearwardly to vforni l v :l lum pintles, the rear endsol said pintles being' bent downwardly, 'forwardly and upwardlj,7 to torni loops having the upper ends ol' their rear arms otlset forwardly, nose guards journaled at their upper ends on said pintles to swing lrom normal posit ions along the inner sidesv ol the loops to positions above said loops to permit access to the parts ol the loops for bending adjustment without interference by the nose guards, and lenssupporting posts secured to the upper oll'set ends of the lront arms ol the loops.
